云信官方文档在这

看官方文档的时候，版本选择最新的V10。

1、CocoPods集成

pod 'NIMSDK_LITE'

2、AppDelegate.m添加头文件

#import <NIMSDK/NIMSDK.h>

3、初始化

NIMSDKOption *mrnn_option = [NIMSDKOption optionWithAppKey:@"6f6568e354026d2d658a7bf5a75cbeac"];
mrnn_option.apnsCername = @"your apns certificate";
mrnn_option.pkCername = @"your push kit certificate";// 初始化配置
V2NIMSDKOption *mrnn_v2Option = [[V2NIMSDKOption alloc] init];
//激活 V10 所有 API，默认使用 V10 的登录接口登录 IM
mrnn_v2Option.useV1Login = NO;
//若仍使用 V9 的登录接口登录 IM
//v2Option.useV1Login = YES;
//是否开启云端服务功能，默认使用本地会话
//    v2Option.enableV2CloudConversation = NO;
//若需要使用云端会话
//v2Option.enableV2CloudConversation = YES;
[[NIMSDK sharedSDK] registerWithOptionV2:mrnn_option v2Option:mrnn_v2Option];

4、登录IM

[[[NIMSDK sharedSDK] v2LoginService] login:@"后端返回的userid" token:@"后端返回的imtoken" option:nil success:^{NSLog(@"登录成功");
} failure:^(V2NIMError * _Nonnull error) {NSLog(@"登录失败：%@",error);
}];

5、获取未读消息数

NSInteger Count = [[NIMSDK sharedSDK].v2LocalConversationService getTotalUnreadCount];

6、获取IM消息列表

[[NIMSDK sharedSDK].v2LocalConversationService getConversationList:0 limit:20 success:^(V2NIMLocalConversationResult * _Nonnull result) {} failure:^(V2NIMError * _Nonnull error) {}];

7、根据用户id查询用户信息

[[[NIMSDK sharedSDK] v2UserService] getUserList:idArr success:^(NSArray<V2NIMUser *> * _Nonnull result) {} failure:^(V2NIMError * _Nonnull error) {}];

8、对一个用户发送IM消息

V2NIMMessage *v2Message = [V2NIMMessageCreator createTextMessage:@"hello"];V2NIMSendMessageParams *params = [[V2NIMSendMessageParams alloc] init];NSString *idStr = [V2NIMConversationIdUtil p2pConversationId:@"10000"];
// 发送消息
[[[NIMSDK sharedSDK] v2MessageService] sendMessage:v2Message conversationId:idStr params:params success:^(V2NIMSendMessageResult * _Nonnull result) {NSLog(@"发送消息成功");
} failure:^(V2NIMError * _Nonnull error) {NSLog(@"发送消息结果：%@==%@",error,idStr);
} progress:^(NSUInteger pro) {}];

9、消息列表代理方法

#import <NIMSDK/NIMSDK.h>//代理
<NIMConversationManagerDelegate,V2NIMLocalConversationListener>//添加会话监听
[[NIMSDK sharedSDK].v2LocalConversationService addConversationListener:self];//移除会话监听
[[NIMSDK sharedSDK].v2LocalConversationService removeConversationListener:self];///代理方法-部分//会话数据云端同步失败，可能为如下原因：网络连接断开；服务异常。可以根据相应错误码确定相关错误原因
- (void)onSyncFailed:(V2NIMError *)error
{
}
//创建会话触发
- (void)onConversationCreated:(V2NIMLocalConversation *)conversation
{}
//被删除的会话ID列表，可以根据该ID列表移除界面上展示的会话数据
- (void)onConversationDeleted:(NSArray<NSString *> *)conversationIds
{}#pragma mark - 会话内容或属性变更时触发
- (void)onConversationChanged:(NSArray<V2NIMLocalConversation *> *)conversationList
{}
#pragma mark - 总未读数变更触发
- (void)onTotalUnreadCountChanged:(NSInteger)unreadCount
{}

10、跳转到消息聊天室

P2PChatViewController *p2pChatVC = [[P2PChatViewController alloc] initWithConversationId:model.conversationId anchor:nil];
p2pChatVC.userid = model.accountId;
p2pChatVC.name = model.name;
p2pChatVC.avatar = model.avatar;
[self.navigationController pushViewController:p2pChatVC animated:true];

11、获取IM登录状态

V2NIMLoginStatus status = [[[NIMSDK sharedSDK] v2LoginService] getLoginStatus];
switch (status) {case V2NIM_LOGIN_STATUS_LOGOUT:NSLog(@"login status = LOGOUT");break;case V2NIM_LOGIN_STATUS_LOGINING:NSLog(@"login status = logining");break;case V2NIM_LOGIN_STATUS_LOGINED:NSLog(@"login status = logined");break;default:NSLog(@"login status = %ld", status);
}
